The problem is that watcher is passing limit=-1 to novaclient when listing servers which will always make at least two API calls to be sure it's done paging: https://github.com/openstack/python-novaclient/blob/13.0.1/novaclient/v2/servers.py#L896 If we can determine before we list servers that there are only a certain number where the number of servers is less than 1000. For example: 4, we should just pass the limit=len(servers) to novaclient and avoid the second call for paging which takes extra time and yields no results.
